Benefits of technology

[0013]An embodiment of the multi-layer material according to the invention comprises a textile cover layer, which is arranged between the functional layer and the coating. The multi-layer material is thus composed of a substrate, functional layer, cover layer, and coating. As such, no attempt is made to imitate the surface properties of the textile substrate on the functional layer, but rather a textile cover layer is provided which, like the substrate, allows for partial penetration of the coating formulation on account of its porous structure. As a result, the mechanical anchoring of the coating to the cover layer is comparable to the anchoring of the co

Example

[0029]FIG. 1 is a cross-section through a multi-layer system without a coating. It shows the textile substrate 1 and the functional layer 2 fixed thereon. An adhesive layer 3 is shown between the cover layer 4 and the functional layer 2. The adhesive layer 3 may comprise a hot glue or hot-melt adhesive that becomes connected to the cover layer 4 and functional layer 2 under the influence of pressure and heat.

[0030]The cover layer 4 shown extends beyond the functional layer 2, such that the cover layer 4 overlaps with the edges of the functional layer 2. This overlap protects the functional layer 2 against locally applied forces that could facilitate detachment of the functional layer 2 from the textile substrate 1.

[0031]In the figure, the cover layer 4 is shown thinner than the substrate. Regardless of the thickness, both layers can be produced from the same yarn.

[0032]FIG. 2 is a plan view of an exemplary embodiment of a multi-layer material having openings 6 in the cover layer 4 a...

Abstract

Please replace the current Abstract with the below language:
A multi-layer material comprises a textile substrate layer, a functional layer arranged on the textile substrate layer, and a coating covering the functional layer and the textile substrate. The multi-layer material further includes a textile cover layer arranged between the functional layer and the coating. An adhesive layer is arranged between the functional layer and the textile cover layer. The textile substrate is woven or knitted from one yarn and the textile cover layer is woven or knitted from an identical yarn.

Description

CROSS REFERENCE TO RELATED INVENTION[0001]This application is a national stage application pursuant to 35 U.S.C. § 371 of International Application No. PCT / EP2020 / 074136, filed on Aug. 28, 2020, which claims priority to, and benefit of, German Patent Application No. 10 2019 123 664.9, filed Sep. 4, 2019, the entire contents of which are hereby incorporated by reference.FIELD OF TECHNOLOGY[0002]The present disclosure relates to a multi-layer material having at least one functional layer and a coating.BACKGROUND[0003]In the field of textile coating, it is known to provide textile substrates with a coating, for example a polymer coating. The coating is applied as a coating formulation to the textile substrate, where it can penetrate into the substrate at least in part on account of the porous structure of the substrate. The adhesion of the coating—which is produced, for example, by means of vulcanization—to the substrate is predominantly based on mechanical anchoring.[0004]It is also k...
